CHARLES S. BOCK,V 0F CHICAGO, ILLINOIS.

HAIR-PIN.

Application filed April 5, 1916.

To all 'whom t may concern:

Be it known that I, CHARLES S. Boon, a citizen of the United States, residing at Chicago, in the county oi' Cook and State of Illinois, have invented new and useful Improvements in Hair-Pins, of which the following is a specilication.

This invention relates to pins employed for holding ladies hair, and its object is to provide a novel and improved pin of this hind which can be securely vanchored in the hair so that it will not accidentally drop out of the same, and which can also be readily removed at will without getting caught in the hair.

rIhe object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may Ibe better understood, reference is had to the accompanying drawing forming a part of this specification.

In the dra-wing,

Figure 1 is an elevation of the device partly in section;

Fig. 2 is a similar View showing the parts `in another position;

Fig. 3 is an enlarged detail on the line 3 3 of Fig. 2, and

Fig. et is a. cross section on the line L1 1 of Fig. 2.

Referring specifically to the drawing, 10 denotes a pin in the form oi a tube or sheath which is tapered and closed at one end, as indicated at 11, the other end being open and provided with any suit-able ornament 12 which also serves as a stop to prevent the pin from being pushed too :tar into the hair.

lVithin the pin is slidahly mounted a rod 13 having an ornamental head 141 at its outer end. This rod is provided with a series of spurs 15, the same being pivoted to the rod as indicated at 16. At the points where the spurs are attached to the rod the latter is flattened. The spurs are positioned to project from opposite sides of the rod in alternate order, and their outer ends are sharp.

Specification of Letters Patent.

Patented Mar. 13, 1917n Serial No. 89,094.

In the wall of the pin 10 is a series of apertures 17 positioned to correspond to the spacing and the location of thc spurs 15, so that the latter may be passed therethrough to project from the pin, the apertures having` suliicient length to allow the spurs to swing therein.

In use, the pin 10, with the rod 13 housed therein, is pushed into the hair by holding the head 14. The spurs 15 normally project from the pin rearward so as not to im-v pede the insertion thereoix into the hair, and they are held in this position by the tendency of the rod to advance in the pin due to the push on the head 14;. The spurs are thus embedded in the mass of hair so that the device cannot of itself withdraw and lit is thus securely held. To remove the device, the head 14 is grasped and the rod is pulled slightly from the pin, the latter being held stationary. This results in the spurs swinging forward as shown in Fig. 2, and as they now @tier no resistance to the withdrawal of the device, the same can be pulled out of the hair. The rod, adjacent to its head, has

a stop collar 18 opposite an internal flange 19 at the open end of the pin to limit the outwardv movement of the rod.

I claim A device of the character described, comprising a tubular pin, a slidable rod housed in the pin and projecting from one end thereof, and pivoted spurs carried by the rod, the side of the pin having apertures through which the spurs project and in which they are free to swing, said spurs projecting obliquely from the pin and being swung by sliding the rod, and pointing rearward with respect to the pin at the limit of the sliding movement of the rod in one direction, and forward at the limit of the sliding movement of the rod in the opposite direction.

In testimony whereof I affix my signature.

CHARLES S. BOCK.
